About this study

Official title: An Open-label Phase I Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Anti-tumor Activity of CREPT-618 in Patients With Locally Advanced Hepatocellular Carcinoma

This is a single-center, open-label, dose-escalation Phase I clinical study designed to evaluate the safety (incidence of adverse events), maximum tolerated dose (MTD), optimal biological dose (OBD), and recommended Phase II dose (RP2D) of CREPT-618 in adult patients aged 18-75 with locally advanced hepatocellular carcinoma who have failed standard treatment.

The study adopts a 3+3 dose escalation design for dose climbing, primarily consisting of three dose groups: low dose, medium dose, and high dose. Patient enrollment and dose escalation in each group will be based on safety evaluation results. Pharmacokinetic parameters and preliminary efficacy indicators will also be assessed.

Read the detailed description

This is a single-center, open-label, dose-escalation Phase I clinical study designed to evaluate the safety (incidence of adverse events), maximum tolerated dose (MTD), optimal biological dose (OBD), and recommended Phase II dose (RP2D) of CREPT-618 in adult patients aged 18-75 with locally advanced hepatocellular carcinoma who have failed standard treatment.

The study employs a 3+3 dose escalation design for dose titration, consisting of three primary dose groups: low dose, medium dose, and high dose. Patient enrollment and dose escalation in each cohort will be based on safety evaluation results. Pharmacokinetic parameters and preliminary efficacy indicators will also be assessed.

The study design includes three dose groups, with a total of 7-13 patients. The dose groups are divided into low dose (sentinel dose, 0.5 mg/kg), medium dose (1.5 mg/kg), and high dose (4.5 mg/kg). The low-dose group (sentinel) will enroll 1 patient; the medium-dose group, 3-6 patients; and the high-dose group, 3-6 patients. Each patient will receive single or multiple subcutaneous injections of CREPT-618 administered once every two weeks. Assessment timepoints include safety evaluations, pharmacokinetic (PK) sampling, and efficacy evaluations.

Starting with the sentinel dose, one sentinel patient will be enrolled in the low-dose group and observed for up to 28 days. If no dose-limiting toxicity (DLT) occurs in the sentinel patient, enrollment will proceed to the medium-dose group. Initially, one patient will be enrolled in this group. If no DLT is observed, two additional patients will be enrolled in the medium-dose group. If no DLT occurs in any of these patients, escalation to the high-dose group will begin. If one DLT occurs, one additional patient will be enrolled in the same dose group; if ≥2 DLTs occur, the previous dose will be determined as the MTD.

The high-dose group will enroll three patients, with the possibility of expanding to six if needed. To ensure the trial can escalate to the anticipated effective dose, if no DLTs are observed in the low-, medium-, or high-dose groups, and no changes are observed in objective response rate or liver function indicators, the dose may be adjusted to 9 mg/kg. One patient will be enrolled at this dose level; if no DLT occurs, two additional patients will be enrolled.

If disease progression is observed at the 6-week efficacy assessment, subsequent treatment will involve CREPT-618 administration every two weeks in combination with pembrolizumab. Based on a comprehensive evaluation of safety and pharmacodynamic (PD) data from existing patients, the investigator may adjust the dosing frequency. If higher doses are tolerated and potential benefits are anticipated, dose escalation to a higher dose group is permitted within the same subject (allowed only once).

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing gene therapy in people with Hepatocellular Carcinoma (HCC), run by Cancer Institute and Hospital, Chinese Academy of Medical Sciences at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 24 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Peiwen Ma, M.D. (+86010-87788165, mapeiwen@cicams.ac.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Primary Objective (time frame: From enrollment to the end of treatment at 12 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Jan 2026.
